Germination Problem ?

All the seeds look to have "popped" tap root visible, shell is cracked. germination is successful. Looks like the issue seems to been them dying off as a seedling, could be a few things. looking at your grow in week 1-2 the seeds look over watered and the feed your giving them seems a bit to much for a seedling. That combo is a sprout killer. There is also the risk of dampening off from unsterile/wet growing medium, I help avoid this by using a mycorrhizae inoculant on its first water. one tip that may help, water the medium before u drop the seed in, stir it in a big pot/bowel, you can get the correct consistency before transferring it into the growing vessels. best of luck.
